Title: Communication equipment
Inventor: AMAKASU ATSUSHI
IPC: H04M11/00
Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To surely enable a recovery procedure by providing a means for detecting abnormality at a line control part with a central processing part. SOLUTION: When a central processing part 1-6 detects abnormality in a line control part 1-7 during transmission, the central processing part 1-6 resets the line control part 1-7. At the same time, the central processing part 1-6 disables a driver IC 1-7-5 for line from the central processing part 1-6 about for two seconds. Thus, a control circuit and a transmission circuit turns into high-impedance state for two seconds. Since this state looks as if the line cable is disconnected when watched from the line side, a network can recover a call.

Abstract: PROBLEM TO BE SOLVED: To obtain the high-quality tone quality of sound in an electrolytic capacitor for sound use by a method wherein the electrolytic capacitor for sound use is formed into a constitution, wherein the respective inner terminals of an anode and a cathode are bent in the opposite direction to each other. SOLUTION: An anode inner terminal 21 and a cathode inner terminal 22 are respectively mounted to the rivet 5 on one side of rivets 5 and 6 and the other rivet 6 on the inner surface side of a sealing plate 4. At this time, when the terminals 21 and 22 are respectively mounted to the rivets 5 and 6 responding to each other in a state that the rivets 5 and 6 are curved toward the opposite direction to each other, the terminals 21 and 22 are naturally bent bysymmetrically holding a virtual vertical surface including the axial line of a capacitor element 2 between them following that the plate 4 is made to cover on an open part formed in a packaged case.  Accordingly, synthetic magnetic fields, which are generated in the central part 21a of the terminal 21 and the central part 22a of the terminal 22, become a synthetic magnetic field of a value of H+1/2H=3/2H because the central parts 21a and 22a are bent to the opposite direction to each other and the distance between the central parts 21a and 22a is made apart, the synthesis of the magnetic fields is reduced and the cause of the deterioration of the tone quality of sound in an electrolytic capacitor is reduced.

Title: Resonance type inverter
Inventor: HASUO AKIHO
IPC: H02M7/48
Filed: 1992-09-03
Abstract: PURPOSE:To provide a resonance type inverter wherein it is unnecessary for a resonance oscillation to have an excessive margin in its amplitude and therefore, remarkably small capacities suffice for circuit elements. CONSTITUTION:Owing to a current reactance part on the side of a load, the voltage and current of a resonance circuit are varied violently, and the excitation requirement of the resonance circuit becomes unsatisfied, and as a result, the voltage of the resonance circuit becomes impossible to decrease to zero. In this state, an output S1 of a comparator 13 continues to stay at a high level, and therefore, an output S2 of a monostable multivibrator 15 is reduced to a low level after a fixed time. Thereby, when a voltage-valley-timing sensing circuit 16 outputs a pulse S3, an output S4 of an AND circuit 17 increases to the high level, and in its turn, an output S5 of an AND circuit 19 increases to the high level to switch on an excitation switch 6. 'That is, the excitation of the resonance circuit is restarted forcedly, and the voltage and current of the resonance circuit are prevented from attenuating and stopping.
